I was planning on installing a tiling WM when I got my last laptop (I used to use Ion, so I'm used to the concept and wanted to give it another go), but frankly as much hate as Unity gets, once I had Ubuntu installed I realised that with some keybinding tweaks it was sufficient.
For me I find that even on 25" screens full screen is usually too much. I prefer to split at least once for every screen now. It was different when monitors were 4:3, though. I made things full screen all the time and was happy with it then.
I'm not 100% happy with tiling WMs though, tbh. I find their focus on being completely mouseless and minimalist integration-wise kind of limiting.
I currently use i3wm + tmux + vim. However, I rarely use tmux splitting due to i3wm splitting.
